BACKGROUND OF THE INVENTION1. Field of the Invention
The present patent application for industrial invention relates to a drawer provided with front door and comprising a locking-regulating apparatus of said front door.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
More precisely, a drawer with front door is a drawer composed of a horizontal bottom wall and at least one vertical front edge whereon a front door is fixed.
Said front door, also defined as finishing door, remains visible when the drawer is closed, thus covering the compartment where the drawer is contained.
Said front door is often provided with higher height and/or width than the front edge.
The peculiarity of the devices used to couple said door to the drawer is that they permit to regulate the door after positioning the drawer inside the cabinet.
A drawback of the devices that are currently available on the market relates to the complex regulation of the front door with respect to the drawer.
In order to actuate some of said devices, the drawer must be removed from its compartment, whereas other devices do not provide rapid intuitive locking of the door to the drawer, with the negative consequence that the position of the door can accidentally change when during locking.
EP 0 160 733 discloses a drawer provided with regulation device that does not comprise any bracket fixed to the front edge of the drawer.
BRIEF SUMMARY OF THE INVENTIONThe main purpose of the present invention is to devise a drawer with front door provided with locking-regulation apparatus, which permits to fix the door to the drawer and then regulate the position of the door with respect to the drawer, without accidentally changing the selection position.
The second purpose of the present invention is to devise a drawer with front door provided with locking-regulation apparatus, which permits to fix the front door to the drawer in centered position according to the “X” and “Y” axes.
The third purpose of the present invention is to devise a drawer with front door provided with locking-regulation apparatus, which permits to mount and fix the front door to the drawer without using the fixing screws that are currently used for such an operation, with the inconvenience that the incorrect insertion of said screws during assembly can cause the uncoupling of the door from the drawer.
The fourth purpose of the present invention is to devise a drawer with front door provided with locking-regulation apparatus, which permits rapid coupling and uncoupling of the front door with respect to the drawer.
The fifth purpose of the present invention is to devise a drawer with front door provided with locking-regulation apparatus, which permits regulation according to the “X” and “Y” axes only after actuating specific regulation means according to the “X” and “Y” axes.
The sixth purpose of the present invention is to devise a drawer with front door provided with locking-regulation apparatus, which permits locking the position of the door with respect to the drawer, after actuating said specific regulation means, without actuating a locking screw (provided in the currently available devices), thus accelerating the regulation cycle.
The seventh purpose of the present invention is to devise a drawer with front door provided with locking-regulation apparatus, which permits to fix the front door to the drawer also when the drawer is already mounted on the runners provided in a cabinet.
In order to achieve the aforesaid purposes, the drawer of the invention is provided with an apparatus comprising at least one locking-regulation device that permits to move the door according to a horizontal “X” axis and a vertical “Y” axis with respect to the drawer.
The description of the invention continues with reference to the attached drawings, which only have an illustrative, not limiting value, wherein:
The drawer (C) of the invention comprises a horizontal bottom wall (F) and a vertical front edge (S) whereon a front door (A) is fixed.
Referring to
-
- a bracket (11) frontally fixed to said front edge (S) of drawer (C);
- a cursor (13) fixed on the back of the front door (A);
- a plate (12) fixed to said bracket (11) by means of latch means (14,11a); said plate (12) being positioned between said first bracket (11) and said cursor (13).
The device (1) also comprises regulation means (16,12a) according to “X” axis and regulation means (12b,13a,15) according to “Y” axis, as described hereinafter in detail.
More precisely, said latch means (14,11a) consist in:
-
- a spring clip (14) provided with a pair of wings (14a) with two retention teeth (14b) facing outwards, from opposite sides;
- a rectangular slot (11a) obtained on said first bracket (11) with horizontal development, as shown in
FIG. 4 .
The regulation means (16,12a) according to “X” axis consist in:
-
- a regulation screw (16) provided with stem (16a) and eccentric enlarged head (16b);
- a hole (12a) provided on plate (12) housing the stem (16a) of said regulation screw (16);
- a vertical slot (112) provided on bracket (11) housing the head (16b) of the regulation screw (16).
The operation and advantages of said regulation screw (16) will become clearer after the description below.
Referring to
In order to fix the front door (A) to the front edge (S), the spring clip (14) is inserted, making the pair of wings (14a) elastically snap inside said rectangular slot (11a) (where it can only slide according to “X” axis).
As shown in the attached drawings, said rectangular slot (11a) is provided with knurled profile on lower and upper overlapped sides to increase grip between contact surfaces, and precisely between said overlapped sides of the rectangular slot (11a) and the external surface of the pair of wings (14a); such a technical device is provided in order to guarantee mutual locking between said plate (12) and bracket (11) according to “X” axis, preventing free rightward and leftward sliding of the spring clip (14) inside the rectangular slot (11a).
The regulation screw (16) must be actuated in order to regulate the position of the spring clip (14) inside the rectangular slot (11a), as described hereinafter in detail.
The regulation means (12b, 13a, 15) according to “Y” axis between said first cursor (13) and first plate (12) consist in:
-
- an eccentric screw (15) provided with stem (15a) and eccentric enlarged head (15b);
- a hole (13a) obtained on cursor (13) where stem (15a) is inserted;
- a through hole (12b) obtained on said first plate (12) housing said eccentric enlarged head (15b).
It must be noted that plate (12) and cursor (13) are respectively provided with vertical guide means, consisting in:
-
- vertical slots (122) provided on the plate (12);
- teeth (133) provided on cursor (13), which are housed inside said vertical slots (122), sliding along “Y” vertical axis.
As shown in
According to the attached drawings, the apparatus of the invention advantageously comprises two first locking-regulating devices (1).
The assembly of each of said two first devices (1) provides for:
-
- fixing the first bracket (11) to the front edge (S) of the drawer (C);
- making the cursor (13) adhere to the first plate (12) in order to make said vertical guide means (122,133) cooperate;
- inserting the eccentric screw (15) into the pair of holes (12b, 13a);
- inserting the stem (16a) of the regulation screw (16) inside the hole (12a) obtained on the plate (12);
- fixing the cursor (13) on the back of the door (A), preferably with screws (V);
- inserting the teeth (14b) of the spring clip (14) into the rectangular slot (11a) and simultaneously the head (16b) of the regulation screw (16) into the vertical slot (112).
Referring to
Said means consist in knurls (124,134) provided on the surfaces of plate (12) and cursor (13) adapted to be in contact when the device (1) is assembled in operating condition.
After assembling the front door (A) on the drawer (C), it is necessary to regulate its position.
Regulation according to “X” axis is made by means of the head (16a) of the regulation screw (16), as shown in
By rotating the head (16a) the door (A) is moved rightwards or leftwards, with consequent sliding of the screw (15) inside the horizontal slot (111) and of the spring clip (14) inside the rectangular slot (11a), as shown in
Regulation of the front door (A) according to “Y” axis is made by means of the eccentric screw (15) in order to make cursor (13) slide with respect to the first plate (12).
As mentioned earlier, referring to
Referring to
Moreover, it must be noted that said screw (15) can be actuated from inside the drawer (C) because said bracket (11) is provided with a horizontal slot (111) that houses the enlarged head (15b) of the screw (15), as shown in
All attached drawings illustrate a drawer (C) provided with a niche (N) on the front edge (S) that completely houses said locking-regulation device (1).
